Cavitation bubble characteristic through laser cavitation and high speed photography is investigated. The characteristic data of bubble dynamics,collapse lighting and bubble collapse shock wave is measured based on apparatus of laser bubble measure. It is shown that the laser bubble is a good simulation of single-bubble. The shock wave intensity of plasma bubble expansion and bubble collapse are related to liquid viscidity.The intensity of the bubble collapse lighting is dependent on bubble collapse least size. The intensity of collapse photon is pertinent with liquid surface and steam tension.
